There is not enough infrastructure to cope with so many new houses.
There is no doctor or dentist in the village, the school will not be able to cope meaning that some existing residents may get declined a place for their young children approaching school age. The public transport is very limited and due to the nature of the roads through the village it is not suitable to increase this. Due to the large developments in hethersett there is a huge increase in traffic through the village which the roads will begin to struggle to cope with.
Existing residents are already suffering a decrease in market value in their homes due to the recent new builds, more homes built will only decrease this further and do absolutely nothing to boost the economy of the village.
